Kilowatt Hour Meters


DIN96 energy meters for measuring kWh of individual machines or complete systems. Manufactured to BS5685, IEC521 with a class accuracy of 1% to IEC1036, and supplied in a 96 x 96 mm DIN case. The kilowatt hour meter has a 7 digit non resettable mechanical counter. Pulsed output is available to send to PLC’s data loggers and computers. Analogue mA output is also available.


For monitoring the consumption of electricity in a single or 3 phase system. Savings can made by monitoring and using electricity at the optimum time.
